Although there are plenty of things you DO need to worry about if you want an effective, interview-landing resume, one way to approach the issue is to look at it from the other side: what you DON'T need to worry about.
Whether it's one page or five, depending on the situation, it may work. Rule of thumb is that if a person is reading it, shorter is best, and if an applicant tracking system (ATS) is reviewing it, you can go longer than usual. (It's possible to have a shorter, ATS-friendly resume, but it takes training and skill. I've taken courses every year to stay on top of this topic, for example.)
Although ATS are programmed to search out key words and phrases, they aren't programmed to count pages. If you're writing your own, going longer is acceptable.
2. Pleasing Everyone
No resume will please each person involved in your job search/interview selection: recruiter, manager, or HR staff. Indeed, no piece of marketing is ever written with the expectation of pleasing every consumer, and the resume definitely is a (self) marketing piece.
Burger joints don't speak to the gourmand and your city's elite restaurant doesn't try to entice hungry folk looking for fast service and cheap prices. You have to know your audience and write to that audience's "buying motivators." This marketing terms refers to the needs that must be filled, the problems that need fixing, and the kind of credentials that can fill those requirements - knowledge, skills, experience, talents, etc.
One audience looks for creativity whereas another seeks someone who sticks to processes. Some positions demand acute attention to detail and others a big-picture vision. Know your audience.
If you're trying to please too many audiences you'll end up pleasing no one at all.
3. Special Effects
Fancy fonts, graphic design, colour, logos, and other touches of creativity on their own will NOT land you an interview. It's the resume's substance - content with context - that will reliably land an interview. If you've no gift for using graphic software, don't despair! It's obviously not a skillset you need in your job and the absence of design won't make one tiny bit of difference in whether or not you land an interview.
But your resume must have great content; that's guaranteed. If it doesn't convey that you can solve the problems inherent in the job description, if it's just a long list of skills with no correlation to how these skills saved time, money, reputation, or earned revenues and saved or gained clients, or how they met legislated requirements, followed procedures, avoided or prevented fines and losses - there are sooooo many ways to prove your worth as an employee - unless and until your resume articulates your value, no matter how fancy the layout, you're not landing an interview.
Three things not to worry about, but lots of scorecard items to meet if your resume is to perform and deliver. If you need assistance, New Leaf would love to be of service.
